Definitively not during the strike. to me seem to be done with a gravel tool, photo of the tool follow:

Second I crop the original image and put the high parts of this to look for. I see the Date, Letters and Mint mark was strike before the zig-zag marks (characteristic of the graving tools).

So must be post strike damage.
